IMPROVEMENT IN OOOKINGSTOVES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, SAMUEL S. UTTER, of the city, county, and State of New York have invented a new and useful Improvement in Stoves and I do hereby declare that the following is a full, clear, and exact description thereof, which will. enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of 'this specification, in which- Figure 1 represents a longitudinal vertical section of this invention.

Figure 2 is a horizontal section of the same taken in the plane indicated by the line a z, fig.

Similar letters of reference indicatelike parts.

This invention consists i n the arrangement of a secondary air-chamber and a separate plate under the bottom part of the back plate of the fire-place of a stove, in such a manner that an additional space is obtained for heating the air before the same is allowed to pass to the main air-chamber, and through it to the fire; and furthermore, by said secondary air-chamber the front oven plate is prevented from burning. It consists, further, in the arrangement of air-channels leading from the back plate of the stove to the lower part of the back oven plate, in combination with the air-chamber under back plate of the fire-place, in such a manner that the vapors rising from the articles to be baked are free to escape, and a supply of hot air is carried in the oven and to the fire,vand thereby the process of baking is facilitated and the gases emanating from the fire are consumed more perfectly than in ordinary gas-consuming stoves. i v

A represents a stove which is provided with a fire-place, B, in tlfe ordinary manner. The heated gases and products of combustion emanating from the fire in the fire-place pass over the top plate a, of the oven 0, to the escape-pipe D. The front oven plate is protected by an air-chamber, c, which is supplied with heated air from the secondary air-chamber d. This air-chamber protects the front oven plate,-and it communicates through a series of holes, e, with the interior of the oven G, and through aseries ofl1oles,jf, with the main air-chamber c. By these means the heated air from the oven finds access to the secondary air-chamber d, and after having been still further heated, it passes in the main air-chamber, and through thisto the fire. The oven is" supplied with air through air-channels, g, which run on the sides of the central smoke-channel it, (see fig. 2,) and'communicate through openings, 2', in the back plate of the stove, with the open atmosphere, and through openings, j, in the back plate of the oven, with the interior of said oven. If the damper k is closed, which is always the case While baking, the heated gass and products of combustion pass down. through the outside smoke-channels -Z, returning through the central channel 72, to the escape pipe; and in making this circuit said heated gasesare in close contact with the air-channels g, and the air contained in said channels is highly heated. If the oven is well closed the upward draught of the air in the oven through the air-chambers d and 0 causes a'downward draught of the air in the air-channels g, and the heated air is'suingfrom the inner openings j of the channels; passes over the articles to be baked and carrics off the vapors rising from the same, and it enters the secondary air-chamber d in a highly heated state. By this arrangement the process of bakingis facilitated, and the air which is admitted through the air-chambers 0 (Z to the heated gases and products of'combustion, is highly heated before it is allowed to come in contact with said gases, and the object of consuming said gases is effected in a much more perfect manner than it iswhen cold air is brought iu-contact with them. By effecting a perfect consumption of the gases a considerable saving in fuel is efi'ected, and a stove is obtained which is durable, which consumes a comparatively small quantity of fuel, and which isso constructed that its baking capacity is superior to that of other stoves of the same size.

What I claim as new, and desireto secure by Letters Patent, is-

The air-channels g g, arranged within the smoke-channels Z Z, and employed in connection with the main chamber a, and additional chamber 01, as and for the purpose specified.
